[Anomalies of atrioventricular valves in origin of the aorta and pulmonary artery from the right heart ventricle].
Anomalies of the atrioventricular valves may influence essentially the choice of the method and volume of surgical intervention in origin of the aorta and pulmonary artery (PA) from the right ventricle (RV). The results of morphological study of 55 heart specimens with origin of the aorta and PA from the RV are analysed; structural anomalies of the atrioventricular valves were revealed in 19 of them (34.5%). The anomalies were surgically significant only in 16.4% of cases. Isolated anomalies of biventricular attachment, simultaneous biventricular attachment and displacement of one of the atrioventricular valves, and anomalous chordae and supernumerary fibrous structures connected to the atrioventricular valves, etc. were the most commonly encountered anomalies of the atrioventricular valves in origin of the aorta and PA from the RV. The frequency and complexity of anomalies of the atrioventricular valves in origin of the aorta and PA from the RV were determined by the morphology of the cardiac complex, the type of the anomaly, and the side involved in the pathology of the atrioventricular valves. The complexity of the atrioventricular valve disorders in such cases could influence noticeably the volume of the surgical intervention. Anomalies of the atrioventricular valves in origin of the aorta and PA from the RV were encountered most frequently in malposition of the heart or discordant atrioventricular connection. The frequency of anomalies of the tricuspid valve was much higher than that of mitral valve anomalies, but the last named were surgically significant in most cases as a rule.
